The Gear shaping process, like all gear manufacturing processes, has been enhanced by the application of CNC Technology. In the case of the gear shaping process the “partial” application of CNC Technology first occurred in 1982. While virtually all gear cutting and grinding machines have had their axes of motions converted to CNC, the development of a CNC electronic helical guide for the gear shaping process was delayed for technological reasons. The following questions will be discussed and answered: • Why is a helical guide necessary in the gear shaping process? • What had delayed CNC technology from being applied to the helical guide principle in the gear shaping process? • How has the addition of the electronic guide CNC Technology impacted the gear shaping process? • Have lead quality and productivity rates been aversely affected by the addition of the electronic guide feature? • How might this increase in flexibility, by using an electronic guide in the shaping process, be applied to real life applications?

Gear Shaping

The machining of cylindrical gears by gear shaping with gear wheel-cutter has accompanied of known cutting errors met at rolling gears cutting: pitch error, total pitch error, profile tooth error, circular runout, etc. The technical papers consider that two aspects can analyze gears shaping precision with gear wheel-cutter: first by the analysis of profile gear cutting errors, and second by profile gear cutting errors in “closing zone of teeth gear”, with a main factor according of stiffness machine tools. The analysis of stiffness machine has done with the values displacements and relative rotations of machine subassemblies to a fixed datum system and two mobile datum systems, in dependence of load applied during idle running or gear shaping process, could be defined three stiffness’s: static, quasi-static and dynamic stiffness. During the cutting process, the variation predictable distance between cutter axe and wheel-workpiece axe is important. This study is carrying out by stiffness machine analysis in radial direction of OY axe. The paper has proposed a method of quasi-static stiffness machine determination of gear shaping process with wheel-cutter. During cutting process occurs altering positions between subassemblies of ram-toolholder and rotated table, even is used finishing working conditions. The research has done by an integration system “force-displacement”, formed by a dynamometer adaptable of gear machine-MD 250, which allowing the acquisition of cutting forces on three axes and displacements of ram-toolholder-workpiece during machining process. The measurement has done in “closing zone of gear”, respectively the outside of that, due to determination of stiffness machine tools. In addition, this research presented the assessing of working accuracy of gear shaping machine with gear wheel-cutter.

Large gear is widely used as a key component of heavy machineries. Gear shaping is the most commonly process of large gear manufacturing. For the design of large gear shaper, the determination of its main driving force depends on the empirical formula. However, its result has shown that the main driving force is much larger than what really needs, which produces a lot of waste. A novel analytical method is proposed in this paper. According to this method, the cutting area can be calculated precisely, and the design of main driving force will be more reasonably, it also provides the theoretical foundation for the design of large gear shaper.

The digital twin (DT) is undergoing an increase in interest from both an academic and industrial perspective. Although many authors proposed and described various frameworks for DT implementation in the manufacturing industry context, there is an absence of real-life implementation studies reported in the available literature. The main aim of this paper is to demonstrate feasibility of the DT implementation under real conditions of a production plant that is specializing in manufacturing of the aluminum components for the automotive industry. The implementation framework of the DT for engine block manufacturing processes consists of three layers: physical layer, virtual layer and information-processing layer. A simulation model was created using the Tecnomatix Plant Simulation (TPS) software. In order to obtain real-time status data of the production line, programmable logic control (PLC) sensors were used for raw data acquisition. To increase production line productivity, the algorithm for bottlenecks detection was developed and implemented into the DT. Despite the fact that the implementation process is still under development and only partial results are presented in this paper, the DT seems to be a prospective real-time optimization tool for the industrial partner.

Gear Shaping

In this paper, the gear shaping of some planetary gear was simulated. The simulation results show that via the gear shaping process, the gear tooth surface on the left has a single tooth pitch deviation of about 1.2 um, and the gear tooth surface on the right has a pitch deviation of 1.1 um, accordingly. By combining the simulation of two-dimensional and three-dimensional gear shaping models, this paper can not only realize accurately the gear shaping process of the planetary gear, but also provide some certain reference for the gear shaping processing.

Abstract Gear shaping process is a generation process by which precision gears can be produced. In some cases, because of the generation motions, interference conditions exist in the process. These interferences may introduce preferable conditions on the gears produced, in a few cases. Such limiting conditions are presented here, after allowing for the trimming of the profile due to these interferences.

PurposeConstruction manufacturers predominantly rely upon antiquated manual design and production processes and procedures because they lack technical skills needed to automate working practices. This paper aims to automate manufacturing processes by optimising the utilisation of BIM digital objects (BDO) via the development of a conceptual model. Concomitant objectives seek to reduce design errors; eliminate unnecessary costs; automate the generation of quantity bills; and maximise productivity performance.Design/methodology/approachAn inductive approach was adopted through a post positivist epistemological lens set within the context of a case study of a small- and medium-sized enterprise. From an operational perspective, both qualitative and quantitative data were collected and analysed via a novel four-phase waterfall design, namely, literature diagnosis; recording contemporary practice; mapping manufacturing workflow and procedures; and evaluation and proof of concept development.FindingsThe work illustrates that BDO enhances manufacturing workflow, reduces product manufacturing lead time and augments quality assurance throughout the whole life cycle of a manufactured product. The conceptual model developed provides a pragmatic and comprehensive solution to automate construction manufacturing procedures and to improve the facilitation of information exchanged between all stakeholders involved.Originality/valueThis study presents the first comprehensive case study of BDO application within a manufacturing context. Future research is however, needed to test and validate the conceptual model presented in practice. In doing so, the model can be further refined using practitioner input and real-life manufacturing processes and procedures.
